Once Human Incendiary Blast Guide
In Once Human, Incendiary Blast refers to the explosive effect that is caused when a flaming projectile directly hits an enemy or a surface. This is a specific type of blast needed to eliminate a Tangled Vine during the Treant’s Seasonal Challenge. Now, it is important to ensure that the explosive hits the desired enemy part/surface directly. In case, you are able to cause damage through fire spread out by the explosion, it will not count as Incendiary Blast. It is mandatory to cause damage through the initial impact of the explosion, this makes the timing of the attack the most crucial part of this explosion.
Defeating Tangled Vine With Incendiary Blast
One of the earliest seasonal goals in Once Human where you will need to execute a perfect Incendiary Blast takes place around Level 15. This challenge takes place against Treant who is a powerful Monolith boss at the Gaia Cliff Monolith in Broken Delta. Defeating this boss while executing an Incendiary Blast is tricky and requires you to choose a compatible weapon.
Weapon For Executing Incendiary Blast

While explosives like grenades exist in Once Human, Molotov Cocktails remain one of the most reliable weapons to execute an Incendiary Blast. You need to aim and time your Molotov cocktail perfectly under the Treant’s vine to accomplish the seasonal goal challenge.
You can get your hands on the Standard Molotov Cocktails through Storage Crates which can be found scattered across the Once Human world. You can also improvise this explosive after you have unlocked Tier 3 of the Crafting tab in your Memetics Menu by using these resources:
- Glass x 5
- Carbon Fiber Fabric x 6
- Sulfur x 6
- Boiled Water x 2
